PHP Array Exercises : Find unique values from multidimensional array and flatten them in zero depth Last update on February 26 2020 08:09:35 (UTC/GMT +8 hours) PHP Array… you can use array_values($twoDimensionalArray) to get values , and array_keys($twoDimensionalArray) to get keys of an array. The following code show how to flatten a multidimensional array into a single one-
  $value) { if (is_array($value)){ $return = array_merge($return, array_flatten($value)); } else { $return[$key] = $value; } } return $return; } $array = Your array $result = array_flatten($array); echo '
'; print_r($result); There are two commonly used functions for the purpose of converting a multi-dimensional array into a single-dimensional array.. The two-dimensional array is an array of arrays, so we create the array of one-dimensional array objects. Elements can be accessed using dimensions as array_name [‘first dimension’] [‘second dimension’]. array_combine. You can also use Underscore.js _.flatten() with Examples. A better approach, I think, is to flatten a multidimensional array into a single dimension, make a single call to array_diff, then (if needed) expand it back out … For this purpose, the numpy module provides a function called numpy.ndarray.flatten(), which returns a copy of the array in one dimensional rather than in 2-D or a multi-dimensional array.
